Question

我试图为String数组设置TextAdapter。基本上它是一个下拉菜单，其中包含与用户想要购买的商品尺寸相关联的字符串列表。

private void SetupSpinner(String[] drawables) {
    Spinner spinner = (Spinner) view.findViewById(R.id.spinner_sizes);
    spinner.setAdapter(new ImageAdapter(getActivity(), R.layout.row, drawables));
}

public class ImageAdapter extends ArrayAdapter<String> {

    private String[] drawables;

    public ImageAdapter(Context context, int textViewResourceId, String[] drawables) {
        super(context, textViewResourceId);

        this.drawables = drawables;
    }

    @Override
    public View getDropDownView(int position, View convertView, ViewGroup parent) {
        return getView(position, convertView, parent);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        TextView view = new TextView(getContext());
        view.setText(Integer.parseInt(drawables[position]));

        return view;
    }
}

我让它与drawables合作，但效率低下。我不想为每个尺寸选项制作图形。无论如何，所有人都非常感谢！

创建xml custom_spinner

unsigned long Layer::GetNumNeurons()
{
    return Neurons.size();
}

然后将微调器放在您需要的主xml中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="vertical">
<TextView
android:id="@+id/text_main_seen"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
<TextView
android:id="@+id/sub_text_seen"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />

然后在你的班级

 <Spinner
    android:id="@+id/spinner_show"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="100px"
    android:drawSelectorOnTop="true" />
